Description

Self-propelled combine harvester with step shaker

The invention relates to a self-propelled combine harvester with a step shaker, the individual steps of which are provided with coverings with grain passage openings, as well as with an attached corn picker.

Combines of the above-mentioned type work satisfactorily in maize threshing when only the grain is to be separated from the grain-spindle-lyset-leaf mixture. A combine harvester constructed in this way, however, cannot be used if only the lizy leaves and a part the spindles are to be excreted, while the grain and a large part of the spindles are to be collected in the grain tank (This grain-spindle mixture is processed into high-quality cattle feed). To do this it is through the DT-OS 2 320 081 known to provide a pull-out pocket with a sieve lying above it at the end of a step shaker, so that the spindles falling from the step shaker can pass through the sieve onto the bottom of the pocket and from there into the Grain tank arrive. It has been shown in practice that only a far too small proportion of spindles can be absorbed in this way.

The present invention is therefore based on the object to create a combine harvester of the type described in more detail at the outset, which, on the one hand, meets the requirements placed on it with regard to collecting a large part of spindles fulfilled in a satisfactory manner, which on the other hand can also be used without major renovation work if only grain should get into the storage tank. This is achieved according to the invention in that the covering at least a step has rake-like extensions at its rear end seen in the direction of material conveyance, free the this

Level partially protruding beyond the next level, with the covering of the latter in its covered by the extensions Area has at least one large section compared to a grain passage opening. After a Another feature of the invention are the rake-like extensions made of stepped and reinforced Formed sheet metal strips whose distance from one another are greater than the diameter of a spindle. In an advantageous way and way, the step extensions can be removed individually or as a whole. An essential feature of the invention can be seen in the fact that the cutouts can be wholly or partially covered. With a combine harvester, its step shaker are designed in this way according to the invention, a large part of the spindles can be made from the spindle-Lieschen mixture because there are rake-like extensions behind each stage of a stage shaker which the spindles can fall through while the lizy leaves are transported further towards the straw cover will. The sections of the step coverings, which are located below the extension, are of course so large, that the spindles can fall through. If only a few spindles are to be removed, those under the extensions The cutouts located more or less covered, so that the spindles falling through between the rake bars from the step below in the direction of the straw drop hood to get promoted. Another advantage of such a trained combine harvester is that only by covering the cutouts completely, for example, also threshed grain can be.

In the following, the invention will be based on an exemplary embodiment and several of this schematically depicting figures are explained in more detail. It shows:

With a self-propelled combine harvester is referred to, the has a corn picker 2 at its front end. The corn cobs picked by the corn picker 2 then arrive as known from the threshing organs in which the grains are excreted. Most of the corn kernels come from transported here by a screw directly into the grain tank. The other part arrives with the lizards and the spindles as a mixture on the step shakers, of which only one 3 is shown. Should the crop now be used for feeding in are used in animal husbandry, one is interested in the largest possible possibly also precisely definable proportion from spindles and spindle fragments into the grain tank and then crushed and ensiled this mixture. For this purpose, the individual stages of the step shaker 3 are divided by several in the direction of travel of the combine harvester extending Schüttlerreiter 4 extended, the distance between the parallel tabs 4 is so large that Spindles can fall through. Below these shaker tabs 4 are the shaker pads 7 in areas 5 and 6 cut away, so that relatively large openings 8 arise through which the spindles or spindle fragments on the lower the step shakers located preparation floor, not shown, and from there fall onto the sieve box. the Lies are transported via the shakers to the area of the discharge hood 9 and fall onto the field. The openings 8 can be partially or completely covered so that, on the one hand, the spindle portion is determined by the partial covering can be, on the other hand, because of the complete cover, the shakers covered in this way can also be used when only grain should get into the tank. In the example shown, only two stages of the step shaker are extended and the shaker coverings are cut out below these, so naturally all or fewer shaker stages can also be used according to the invention be trained. Furthermore, the shaker
